Setting up RAID

[tony_ong]

Hi,

some question regarding RAID. Let say i setup a RAID, be it RAID 1 or 5, using my MB, in the future if i change MB, i have to reset up the raid from scratch and the data in HDD will have to be wiped out for the new system?

If you use the motherboard RAID, most likely the data will be gone once you change another board. However you might have better luck if you use a dedicated RAID controller which you can transfer. Of course such RAID controllers are not that cheap.

so it means that if i use on board RAID, it will be much better if i have a dedicated ext HDD or something to have a copy of what is in the RAID?

if you use onboard RAID, you might as well just use windows RAID.. (im assuming you are using windows).

Performance is roughly the same since both methods push the workload to the cpu.
Using windows RAID, you can easily "transfer over" to another system also running Windows w/o worrying about the hardware side.

oh. so windows raid is not hardware reliant?

Yes, u can migrate to another system running the same windows version with windows software raid.

Some ppl call Onboard chipset raid (usually intel) fakeRaid because like true hardware raid, u need the same chip on another system to migrate over. So if u change motherboard, v likely u cannot retain data.
However what is "fake" about that is that the workload is still handled by your cpu instead of the hardware raid card.
But with onboard raid, u can achieve something v interesting.
With 2 hard disks, u can have one partition running RAID-1, while one partition running RAID-0.

If using Windows 8 storage space something like raid.
Only can migrate to Windows 8.

I m using win 7 pro. So if I use windows raid I can migrate the hdds to another system without any problems?

The raid 1 and raid 0 is it the raid 10 that Wikipedia mentioned?

1. u can migrate to another win 7 system without any problems.

2. RAID-10 is a different thing. Usually, RAIDs are configured such that if you run RAID-1, the entire 2 disks are RAID1.
If you run RAID-0, the entire 2 disks are RAID0.

What I was talking about is kind of a matrix mix.
Intel RAID allows you to mix the 2 together in separate partitions.
Imagine you have a Partition C:\ that is under RAID-1.
And then a Partition D:\ that is RAID-0.
On each of the 2 disks, split one section using RAID-1 (probably for OS and data), and another using RAID-0 (applications for performance).

Ohoh. I see. Noted. Thanks will try it out when I am free.

The intel raid can be done using the intel rapid storage technology right?

Thanks for the link

Seem like rapid storages is a different thing.

 

[Asure7]

Same thing, just different names for different versions.
Intel Rapid Storage Technology is the name of the current version

Ohoh. I see. Will try it when I m free when I get another hdd

Hi
If u use intel chipset raid on the mobo, if I recall correctly, u should be able to migrate to a new mobo in future with intel newer chipset. Since all these are software raid, I don't think it is dependent on your actual intel chipset. I've only tried on mirror. Worst case I can always rebuild. Just do a backup just in case. I did this last yr. just in case I remember wrongly.
